摘　　要：实时数据库系统是DCS组态软件体系结构的关键部分。通过分析实时数据库的特点和DCS系统的使用要求,将系统设计分为实时数据库结构设计和实时数据库管理程序设计两个部分。实时数据库结构主要根据DCS系统的特点和要求来设计,管理程序部分负责实时数据库的产生、在线修改数据、处理其他任务对实时数据库的实时请求以及报警和辅助遥控操作等对外界环境的响应。Real time database is the critical component of architecture of DCS configuration software. Through analyzing the features of real time database and the requirement of operation of DCS, this system design is divided into two parts ： real - time database structure design and real - time database management program design. The design of the real - time database structure mainly based on the features and requirements of the DCS system, management program partly responsible for the generation of real - time database and data modification on - line. The management program also dealed with other tasks real - time requests and the responses of the alarm and auxiliary remote control manipulation of the external environment.
